Is hot dipped galvanised the same as galvanised?

Hot dipping gives a thicker zinc coating than standard galvanising, improving corrosion resistance.

Can I use a washer?

Yes, a matching M8 hot dipped galvanised washer can be seated under the head.

Is it suitable for outdoor use?

Yes, the hot dipped galvanised finish resists corrosion outdoors.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Zenith M8 and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
